問10：尊者，如果坐時觀照「坐、坐」是目的，為什麼還要教我們坐時觀「起、伏」呢？

Q10: Venerable Sir, if noting 「sitting, sitting」 when one is sitting serves one』s purpose, why is one instructed to note 「rising, falling」 when one is sitting?

問10：尊者，如果坐時觀照「坐、坐」是目的，為什麼還要教我們坐時觀「起、伏」呢？

Of course, it serves one』s purpose to note 「sitting, sitting」 when sitting. But if one observes a single kind of object for long, it would become so easy that he may lose balance from little energy and too much concentration. This would result in sloth and torpor andshalloworweakawareness.That』s why one is instructed to observe「rising andfalling」as a main object when one is sitting.

當然，坐時觀坐是目的，但一個人觀照單一目標太長，就會變得太容易觀照，以至于會因為精進力太少、定力太過而失去平衡。這會導致昏沉睡眠和表淺的覺知或無力的覺知。這是為何教你坐時以觀照「起、伏」作為主要所緣。
